The 74HC595 object I wrote for the Parallax Propeller should work for this kit. The number of outputs the driver can control - 4 74HC595’s / 32 lines is an exact match to the number in this kit, and it will allow you to do PWM on all of them independently.

The grey area at the 4 o'clock position in the aerial photo you provided of the parking lot looks suspiciously like water! Do you have a pond next to the parking lot? (I’m wondering if I need to add an “emergency water avoidance” protocol to the robot; or simply fill the cracks in the case with silicone so it’ll float if it falls in.)
